Missoula anchors the southeastern corner of this 1964 survey, where the valley floor begins its ascent into the Lolo National Forest. The landscape reveals a complex network of transportation and industry, with the Northern Pacific and the Chicago Milwaukee St Paul and Pacific railroads running parallel through the corridor. The presence of the US Forest Service Aerial Fire Depot and the County Airport highlights the region's mid-century importance as a hub for regional aviation and forest management.
